Streisand, 76, also sang some song from her new album "Walls", which is out now.
To calm herself down before a performance, she tells herself, "Let go and let god".
In 2016, during an interview, Streisand complained about Siri, saying, "She pronounces my name wrong". Instead of Corden in the driver's seat, as per usual, it's the Academy Award-winning actress-singer at the wheel.
In fact, Streisand confessed, she had stopped performing for 27 years because her anxiety was too intense.
Hey, DMV! Don't rain on Barbra Streisand's parade with your "driving tests".
Tell us what you think! "So what's a better way to change my name than by speaking to Apple?"
"I get scared. I just don't want to disappoint people", she explained.
Later, Streisand recounted the chestnut about how she hailed the ultimate Apple customer support - as in company chieftan Tim Cook himself - when she anxious that Siri was teaching people to mispronounce her last name. "Is that possible?'" she said. "Streisand" with a soft S, like sand on the beach.
Streisand also talked about the time she used Steve Jobs as her personal computer expert. (What's more, it wasn't her first time dialing an Apple boss for help, she shares!) Corden then hails Siri to prove that Babs' last name is now done right.
